A multifunctional bag device according to this invention can be used not only as an ordinary bag, but also to provide a variety of functions by itself or with a sheet and hood contained in the bag. The multifunctional bag device of this invention includes a bag 1 consisting of right and left bag members 1a, 1b that is designed to contain appropriate things in it, a single sheet 2 which is contained in the bag 1 in a folded state, and a hood 3 formed so that it can be loaded on the upper portion of the sheet via fasteners. The bag 1 has handles 6 at the top, and edges of the right and left bag members are connected to each other at the bottom 4, and with a fastener 5 or other opening/closing device which allows the right and left bag members to be unfolded. The sheet 2 is equipped with a fastener 7 or other opening/closing device at peripheral edges to allow a bag 8 to be formed by folding the single sheet in half. With this configuration, the multifunctional bag 1 is a novel bag that can be used not only as an ordinary bag, but also as a pair of seats, a cushion, a lap robe, a sleeping bag, and a hooded poncho.

The invention relates to a process for the preparation of D-(-)-phenylglycine chloride hydrochloride by chlorinating D-(-)-phenylglycine hydrochloride, which as such is prepared in situ from D-(-)-phenylglycine and hydrochloric acid gas, in a solvent. According to the invention chlorination of the hydrochloride is carried out in a non-chlorinated solvent or a mixture of non-chlorinated solvents in the presence of a reaction promoting medium.Chlorination is carried out through the addition of PCl.sub.5, but preferably the PCl.sub.5 is prepared in situ from PCl.sub.3 and Cl.sub.2 gas.
摘要:
The present invention provides a predictive method for selecting organic compounds having useful pharmaceutical activity in a mammal. The method uses volume areas of similar molecules. When specific substituents of the test compound file predetermined volumes, the compound is subject to a binding assay. Only when the binding assay is positive, is the experimental compound recommended for further pharmaceutical evaluation. Example compounds are derivatives of 4-substituted 2,6-diiodophenols of the structure: ##STR1## where R.sup.1 and R.sup.2 are defined as aliphatic or substituted aliphatic moieties or aromatic or substituted aromatic moieties. Useful structures are described. The compounds have useful pharmaceutical properties to treat conditions in a human being, including hyperthyroidism, angina pectoris, arrythmia, and the like.

Compounds of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, n, m, o, p, and q are as hereinafter set forth,and, when R.sub.2 is hydrogen, pharmaceutically acceptable salts thereof with bases, are described. The compounds of formula 1 are potent inhibitors of phospholipases A.sub.2 (PLA.sub.2 's) and are therefore useful in the treatment of inflammatory diseases, such as psosiasis, inflammatory bowel disease, asthma, allergy, arthritis, dermatitis, gout, pulmonary disease, myocardial ischemia/reperfusion, and trauma induced inflammation, such as spinal cord injury.
摘要:
Carboxylates of polar, hydrophilic alcohols of the formula ##STR1## in which R is an unbranched or branched organic radical which contains, as polar members between aliphatic or araliphatic hydrocarbon bridges, ether oxygens, amine nitrogen groups or a mixture of ether and amine groups which can be incorporated into a cyclic structure, where the total length does not exceed 20 members and where, in the case of polyethylene glycol [(CH.sub.2 --CH.sub.2 --O).sub.n ], n indicates the number of the members and is defined as any integer, and R' is an aliphatic or araliphatic radical which has at least one functional group, are suitable as protective groups since they can be introduced selectively into functional groups of organic compounds and eliminated specifically by lipases.
